Hey — that error usually means the integration is missing required data about the person it’s trying to message. If you’re still seeing it, let me know which row you’re looking at. Otherwise, double-check that the person’s info (like name or email) is present in the row before the action runs.
To troubleshoot your Slack integration, first ensure your connection is properly set up by going to Settings > Connections and verifying your Slack account is connected via OAuth.
If you're still experiencing issues, you can edit your integration account by clicking your profile picture, going to Settings, selecting the Connections tab, finding your Slack integration, clicking the ... next to the account, selecting Edit, and updating your account details.
